Given staggered isometric map and a start tile what would be the best way to get all surrounding tiles within given radius(middle to middle)?

I can get all neighbours of a given tile and distance between each of them without any problems but I'm not sure what path to take after that. This feature will be used quite often (along with A*) so I'd like to avoid unecessary calculations.

If it makes any difference I'm using XNA and each tile is 64x32 pixels.

Isometric - precise screen coordinates to isometric

I'm trying to translate mouse coords to precise isometric coords (I can already find the tile the mouse is over, but I want it to be more precise). I've tried several different methods but I seem to keep falling short. For drawing I use: batch.draw( texture, (y * tileWidth / 2) + (x * tileWidth… >>> More
